Change the Location of Velocity.Log File - jboss

Question

I used velocity-1.6.2.jar
my problem that velocity.log is created on the server start under jboss/bin
jboss/bin has read only permission.
and in my appilcation when velocity-1.6.2.jar will be called I have this error:
Caused by: java.io.FileNotFoundException: velocity.log (Permission denied)
I want to change the location of Velocity.Log File
This is the location line in my velocity properties:
# ----------------------------------------------------------------------------
# default LogChute to use: default: AvalonLogChute, Log4JLogChute, CommonsLogLogChute, ServletLogChute, JdkLogChute
# ----------------------------------------------------------------------------
runtime.log.logsystem.class = org.apache.velocity.runtime.log.AvalonLogChute,org.apache.velocity.runtime.log.Log4JLogChute,org.apache.velocity.runtime.log.CommonsLogLogChute,org.apache.velocity.runtime.log.ServletLogChute,org.apache.velocity.runtime.log.JdkLogChute
# ---------------------------------------------------------------------------
# This is the location of the Velocity Runtime log.
# ----------------------------------------------------------------------------
runtime.log = velocity.log

Answer 1

Runtime log can get full path so just direct log to your desrirable folder as /home/velocity.log
runtime.log = /home/velocity.log
Full path and name of log file for error, warning, and informational messages. The location, if not absolute, is relative to the 'current directory'.
Update (27-02-2018)
The log path can also be set programmatically as following:
import org.apache.velocity.app.VelocityEngine;
public class VelocityCustomEngine extends TemplateEngine {
private final VelocityEngine velocityEngine;
public VelocityCustomEngine() {
Properties properties = new Properties();
properties.setProperty("runtime.log", "/home/velocity.log");
this.velocityEngine = new VelocityEngine(properties);
}
}

I know there's an answer. In case you don't want to extend the original VelocityEngine.
You can also new a VelocityEngine instance only changed the "runtime.log" properties before the init() method without any new class.
VelocityEngine velocityEngine = new VelocityEngine();
velocityEngine.setProperty("runtime.log", "/home/velocity.log");
velocityEngine.setProperty(RuntimeConstants.ENCODING_DEFAULT, "UTF-8");
velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
velocityEngine.setProperty("classpath.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
velocityEngine.init();//init method will use the properties(include the log file location) actually.
return velocityEngine;
